GuatemalaAnalista de Sistemas at IGSS
About
At GUATEPLAST, I contributed to modernizing a Human Resources suite from Delphi to .NET and SQL Server. I reduced payroll calculation from approximately six hours to three minutes and report generation from 30 minutes to seconds by restructuring data and stored procedure logic.
At EVOSYS, S.A., I coordinated two developers on projects, assigning tasks, estimating timelines, reviewing progress, and communicating risks. I also developed the backend of an API from scratch with Node.js, Express, and PostgreSQL.
At FORZA, S.A., I developed adjustments and features for the Denarius web and desktop applications. I implemented ways for users to view operation statuses without leaving their screens, working with tables and stored procedures through DBA review and QA validation.
I'm currently an analyst at IGSS, analyzing requirements and implementing changes and new features in institutional applications. I also teach engineering courses at Universidad Mariano Gálvez de Guatemala, where I design projects, exercises, and assessments.
